The fishening v3: Fishing lures. (#86007)

## About The Pull Request
Over half of the line changes are merely from splitting the
fish_types.dm into several files since it was over 1k lines already.

One of the small issues with fishing right now is RNG. You want to get
some specific fish, and you go through all the micromanaging with hooks,
reels and baits only for the random number god to say "nope", and that's
only going to get worse the more fish are in the game.

However, I've a solution: (unconsumable/reusable) fishing lures, each of
which attracts different fish based on different conditions. The only
caveat is that they require to be spun at set intervals (usually 1 to 3
seconds, depending on the lure, with a second-long window). Worry not,
there're visual cues in the form of a green/red light hovering the
fishing float, so you won't get screwed up by the server slowing down or
whatever.
The whole box of lures (12 so far) can be from cargo for the fair price
of 450 credits.

I've also added 5 new fish: monkfish, plaice, pike, another punnier
variant of the pike, perch and squid. The latter is quite special
because of the ink production trait, which lets players use it to blind
others at a close range and when butchered, it yields an ink sac, which
can be processed into a can of squid ink (one less item exclusive to the
produce console), or thrown at people in a sort-of-similar fashion of
banana cream pies (except it's ink).

A few more things in the CL, baitfish are a thing now.

## Why It's Good For The Game
There should be ways to contrast some of the RNG fishing has. After all,
it's only going to get more random the more fish are in the game.
Furthermore, I find it disappointing that a lot of food stuff is
exclusive to the ingredients console and there're no other ways to get
it.

## Changelog

🆑
add: Added fishing lures to the game. They don't get used up like baits
and let you catch specific kinds of fish, though they need to be spun
every few seconds. The whole set can be ordered from cargo for 450
credits.
balance: The magnet hook now removes dud chances.
add: Added five new fish types: perch, two types of pike, monkfish,
plaice and squid. Squids have a fairly special ink production trait,
which lets you use them (unless dead) to ink people face at close range,
and can be butchered for an ink sac, which can either be processed into
canned squid ink, or thrown at someone.
fix: Refactored throwing a little. Some items (specifically
components/elements) won't be triggered when caught. no more plates
shattering despite being caught for example.
add: Goldfish, lavaloops, needlefish and armorfish can now be used as
baits.
